' ELECTROLYTIC TANK.

Application filed December 5, 1923. Serial No. 678,749.

This invention relates to improvements in electrolytic tanks, having forits obJect a. novel form of electrolytic tank in combination with arefrigerator for the purposeof increasing the time required inelectrolitically raising the temperature of certain electrolytes.

It is likewise an object of the invention to provide an electrolytictank of the character mentioned adapted to limit the r1se 1n temperatureof the electrolyte, preventing the further decomposition of certainelectrolytes.

The invention is especially adapted in' preparing sodic hypochlorite. Inthe usual form of tank sodic chlorate is produced in addition to thesodic hypochloride. The sodic chlorate augments in volume with risingtemperature. It is therefore obvious that limiting the temperature andthe time required, the small portion of sodic chlorate and a relativelysmall quantity of hypochlorite will not be decomposed.

Other objects of the invention will be 1n part obvious, and in partpointed out hereinafter.

In order that the invention and its mode of operation may be readilyunderstood by persons skilled in the art, I have 1n the accompanyingillustrative drawing, and in the detailed following description basedthereupon, set out one possible embodiment of the same.

The accompanying drawing is a front elevation, a portion of the caslngbeing broken away.

Referring to the drawing, the numeral 1 designates an electrolytic tankwhich is of the usual well-known construction, while 2 is receiving tankprovided with an open ing to permit introduction of an electrolytic. Arefrigerator 3 is placed between the electrolytic tank 1 and thereceiving tank 2 and in communication therewith through the medium ofpipes 9 and 5 respectively. The electrolytic tank 1 and tank 2 areconnected by a tube 10. y

l The refrigerator 3 is provided with a pipe 6 having one endcommunicating with the pipe 5, the opposite end being closed. A similarpipe 8 is provided in the lower portion of the refrigerator,communicating at one end with the pipe 9 and having its opposite endclosed. These pipes 6 and 8 are substantially horizontal and areconnected by a plurality of distill worms or coils 7,

thepurpose of which will be hereinafter more fully set forth.

In the refrigerator 3 cooling water is circulated by means ofan inletpipe 11 and another pipe 12. The refrigerator is also provided with awater gauge 14..

The tank 2 has an open outlet pipe 15, limiting the amount ofelectrolyte deposited therein, and is also provided with a gauge 13. Thetank 1 has a valved outlet 16 for an obvious purpose.

The mode of operation of the improved device may be stated to be asfollows:

The liquid which is tobe decomposed is placed in the tank 2 by means ofthe opening 4. The cooling water is started circulating through therefrigerator by means of the inlet pipe 11 and outlet pipe 12. Theelectrolytic tank is also put into operation in the usual manner throughthe medium of a switch, not shown.

The liquid in the tank 2 passes through the pipe 5 and into the. pipe 6of the refrigerator 3. From the pipe 6, it passes through the coils 7 tothe pipe 8 and then through the pipe 9 to the tank 2. V

In the electrolytic tank 1, the pressure of the hydrogen, which isproduced by the electrolytic reaction, forces the liquid to rise throughthe tube 10 into the tank 2.

It is obvious that as the circulating electrolyte passes through thedistill worms or coils '7 of the refrigerator 3, theelectrolyte iscooled to an appreciable extent, the degree of cooling being regulatedby the quantlty of circulating water used.

hlanifestly, the construction shown is capable of considerablemodification and such modification as is within the scope of my claims Iconsider within the spirit of my invention.

I claim 1. In a device of the character described comprising incombination an electrolytic tank, a refrigerator, a receiving tank,means for passing liquid from the receiving tank through therefrigerator and thereafter to the electrolytic tank, and means forreturning liquid from the electrolytic tank to the receiving tankoperated by the gas pressure generated within the electrolytic tank.

2. In a device of the charaeterdescr-ibed comprising in combination ahermetically sealed electrolytic tank, a refrigerator, a receiving tank,means for passing liquid from the receiving tank through the retrfi gerator and thereafter to the electrolytic tank, and a pipe connected atone end to the electrolytic tank to receive liquid therefrom and at theother end to the receiving tank to deliver liquid thereto.

3. A device of the character described comprising in combination ahermetically sealed electrolytic tank, a refrigerator positioned abovesaid electrolytic tank, a receiv- 10 ing tank positioned above saidrefrigerator,

a pipe for leading liquid by the action of gravity through therefrigerator to the electrolytic tank, and a pipe connected at one endto the electrolytic tank to receive liquid therefrom and at the otherend to the receiving tank to deliver liquid thereto.

In \vitnessivhereof I have hereunto set my hand.
